Just finished the new post of some of my work(s) mostly i do them on paper in multicoloured pens. I will store those for later and add to them if needed. complete with copyright date and confidential. I wish they would impose my new copyright string as legal. it tells more about the work(s) you are trying to protect. Here is an example
RoaRinG.BiZ-(c)By Philip John Jatzek 13:44.22/14/2022@V1T5W3 ALL RIGHTS RESERVED.
this is an appendature to the existing copyright notice. here it is in text
"<Title of Work>" (c)By <owner> (military hour:minutes).(day/month/year)@(postal code) ALL RIGHTS RESERVED.
with this new format you can see the exact time and date the work was finally completed on as well as where it was created by the postal code. no discrepancies. you know exactly when and where there work was done. good for people spying on you or trying to steal from you as you have the completion of work date and location.. Better then the copyright notices they have now.
